Title: Path searching method for mobile investigating machine
Inventor: SAITO HIROAKI
IPC: G01C21/00
Filed: 1993-08-27
Abstract: PURPOSE:To shorten the processing time for search for a path and to secure the stable traveling of a mobile investigating machine by calculating the topographical flatness to show the topographical state of each of plural local paths reaching a destination and then selecting a path that has the least topographical flatness. CONSTITUTION:The topographical data including the obstacles are acquired by a topographical sensor 4 mounted on an unmanned mobile investigating machine 1, and a path reaching a destination is searched. Under such conditions, an external environment recognizing means 41 acquires the local map data in an external area sensing range based on the topographical data. Meanwhile an inertial sensor 44 sends the correction data to the means 41 due to the shift and the posture change of the machine 1. Then a local path planning means 42 of the machine 1 calculates the topographical flatness set for each local path based on the average topographical height, the scattered value of the tilting degree and the average value of the sloping surface direction in regard of plural local paths that connect together the travelable areas and are reaching the destination from its own position of the machine 1 set on a path searching map. Thus the machine 1 selects a path that has the least topographical flatness as its optimum traveling path.
